Classroom in a book says I should be able to hold the Option key (on the Mac) drag a clip to another point in the timeline, and release it to inserting the clip into the timeline. What's happening for me is that when I Option-drag I'm disconnecting the video from the audio, which is not what the book illusrates. Any insight into how to do this kind of edit with drag and drop would be much appreciated.

I was hoping there was something like a shuffle edit as the book describes, where holding the Option key will allow inserting the clip back into the timeline and rippling the resulting gap to close it.

Thanks Ann. What I would like to do is what's sometimes called a shuffle edit, and is what I believe was the feature the book was trying to describe but didn't work. It's a way to move a clip or group of contiguous clips from one place in the timeline to insert into another place in the timeline and to have the resulting gap automatically close up. I think the only solution, as the Option-drag function described doesn't work, is to use cut and paste insert.
